    2. Influence of axial length on thickness measurements using spectral domain optical coherence tomography

      Influence of axial length on thickness measurements using spectral domain optical coherence tomography

      Purpose:To assess the influence of axial length on spectral domain optical coherence tomography (SD OCT) thickness measurements in patients with subretinal visual implant. Methods:Data from eight emmetropic pseudophakic eyes of eight patients with subretinal visual implant were analyzed retrospectively. These patients participated in the monocentric part of a multicentre trial (www.clinicaltrials.gov number: NCT01024803). The axial length was measured in three short (< 22.5 mm), three medium (22.51-25.50 mm) and two long (> 25.52 mm) eyes. Using Heidelberg Spectralis, the known thickness of subretinal implant microchip (70 µm) was measured on 15 images per eye ...

    3. Comparison of choroidal thicknesses using swept source and spectral domain optical coherence tomography in diseased and normal eyes

      Comparison of choroidal thicknesses using swept source and spectral domain optical coherence tomography in diseased and normal eyes

      Background/aims Choroidal thickness measurements are reported to differ between swept source optical coherence tomography (SS-OCT) and spectral domain OCT (SD-OCT). This study aimed to assess the comparability of choroidal thickness measurements using SS-OCT and SD-OCT devices among patients with retinal diseases and normal participants. Methods In a prospective cohort study of 100 subjects, comprising patients with retinal disease and normal volunteers, OCT scans were performed sequentially with the DRI OCT-1 and Spectralis OCT using standardised imaging protocols. Subfoveal choroidal thicknesses were independently measured by masked reading-centre certified graders. Paired t tests and intraclass correlation coefficients (ICCs) were used to ...

    4. Hemifield pattern electroretinogram in ocular hypertension: comparison with frequency doubling technology and optical coherence tomography to detect early optic neuropathy

      Hemifield pattern electroretinogram in ocular hypertension: comparison with frequency doubling technology and optical coherence tomography to detect early optic neuropathy

      Background: To assess the sensitivity and specificity of hemifield pattern electroretinogram (HF-PERG) for detecting early retinal ganglion cell (RGC) damage in ocular hypertensive (OH) patients. Methods: Fifty-two OH patients (mean age 56±9.6 years) with an intraocular pressure (IOP) >21 mmHg were assessed. All subjects underwent HF-PERG, optical coherence tomography (OCT), and frequency doubling technology (FDT) visual field. Results: OH patients showed a significant increase of peak-time of the N95 ( P =0.027) compared to controls. The amplitude of the N95 of the lower and upper HF-PERG showed significant differences ( P =0.037 and P =0.023, respectively) between ...

    5. Difference in Subfoveal Choroidal Thickness between Two Spectral-Domain Optical Coherence Tomography Systems

      Difference in Subfoveal Choroidal Thickness between Two Spectral-Domain Optical Coherence Tomography Systems

      Purpose To determine the difference in subfoveal choroidal thickness between two spectral-domain optical coherence tomography (SD-OCT) systems in normal eyes and eyes with retinal diseases. Methods Thirty-three normal eyes and 49 eyes with retinal disease (13 eyes with diabetic retinopathy, 28 eyes with epiretinal membrane and eight eyes with macular hole) were enrolled in the study. Subfoveal choroidal thicknesses were measured by 3 observers using the enhanced depth imaging technique of Heidelberg Spectralis® and the high-definition five-line raster scan of Cirrus HD-OCT® using calipers within the program. Differences between the measured values were analyzed with a paired t -test in ...

    7. Spectral-domain optical coherence tomography findings in polypoidal choroidal vasculopathy suggest a type 1 neovascular growth pattern

      Spectral-domain optical coherence tomography findings in polypoidal choroidal vasculopathy suggest a type 1 neovascular growth pattern

      Purpose: To report spectral-domain optical coherence tomography (SD-OCT) findings in polypoidal choroidal vasculopathy (PCV). Patients and methods: Seventeen eyes of 15 consecutive patients diagnosed with PCV based on typical clinical and angiographic findings were imaged with macular SD-OCT including line scans passing through the polyps. Results: SD-OCT findings included typical and atypical retinal pigment epithelial (RPE) detachments and subretinal and intraretinal fluid in all eyes. In the areas corresponding to the polypoidal lesions, well-delineated round-oval, sub-RPE cavities were present and were adherent to the posterior surface of the detached RPE above Bruch membrane. No retinal or choroidal connections to the ...

  3. Quotes about Heidelberg Engineering

    1. I am becoming a big fan of spectral-domain OCT, especially Spectralis [Heidelberg Engineering, Vista, Calif.]...To this point with time-domain OCT, I have not been convinced that you can use this technology to follow patients over time. Now, with the faster image acquisition and better axial resolution we see with SD OCT, there is better quantitative peripapillary retinal nerve fiber layer measurement for glaucoma management. The improved accuracy of the OCT segmentation allows for better long-term evaluation of patients.
